Explanation:
Detailed explanation-1: -Sensory receptors occur in specialized organs such as the eyes, ears, nose, and mouth, as well as internal organs. Each receptor type conveys a distinct sensory modality to integrate into a single perceptual frame eventually.
Detailed explanation-2: -This process is called sensory transduction. This occurs when a stimulus is detected by a receptor which generates a graded potential in a sensory neuron.
Detailed explanation-3: -Chemoreceptors-They respond to chemical stimuli. E.g. receptors for taste, i.e. gustatory receptors and smell, i.e. olfactory receptors are examples of chemoreceptors. Gustatory receptors are present in the taste buds present over the tongue.
